When my 4gb unit gets filled is it easy to transfer everything in storage to a 4, 8, or 16gb sd card in one shot? Willl there be ANY problems on the tranfer such as sound quality loss -or- am I better off recording directly to external memory in the 1st place? Is it easy to do? The reason I'm asking is because I might buy another mp3 player that's smaller for carrying around and that has an SD card slot and uses a AAA battery. For those wondering I do like and need the Pilot since I'm only doing Line-In recording and it's one of the few players that offers that along with memory expansion for a decent price

One other unrelated question, Is it ok to record or listen to the Pilot while plugged into a wall or car charger? Thanks
